ETL
ETL, which stands for Extract, Transform, Load, is a crucial data integration process used to consolidate data from various sources into a single, coherent data store. This process involves three key steps: extracting data from multiple sources, transforming it to meet specific business requirements, and loading it into a target system, such as a data warehouse. ETL has evolved significantly since its inception in the 1970s, becoming essential for organizations to manage and analyze their data effectively. By streamlining data processing, ETL enhances productivity and supports informed decision-making across businesses.
